Visa information

It would be really good if we could get some information about visas ending from June 1st. The process as to what we can do, extensions or if we need to leave.
Would really help ease some stress.

My working holiday visa ends June 1st and it seems near impossible to get from Glasgow to London for a flight to Australia and also getting a company to ship my stuff back to Australia before June 1st will probably be near impossible.
Information would be great, an extension even... Anything!
